The Nathaniel Narbonne High School (Harbor City, Cal.) product is considered by most a 3-star recruit. Scout.com has him as the No. 50 wide receiver prospect, while 247Sports.com gives him a rating of 84.

Here's a video of A.J. Richardson talking about his future at Boise State. bit.ly/11VGraj

Richardson's commitment is particularly significant for the Broncos after the team last month lost another impressive wide receiver recruit, Jack Austin, to Cal.

In an interview with the Idaho Statesman, recruiting guru Huffman said that Scout.com actually had Richardson ranked higher than Austin:

He’s such a big, physical receiver. He’s not an explosive receiver, but he’s not slow. … He’s kind of fallen into Boise State’s lap. Essentially they’re trading him for Jack Austin. We had him ranked higher than Jack Austin.

Richardson is a great addition to an already good 2013 class for Boise State. The Broncos are expecting to sign three other wideouts by the end of the day, with Jake Roh, Kendal Keys and Tanner Shipley expected to come aboard.

ESPN.com has Shipley ranked at No. 206, Roh at No. 205, Keys at No. 103 and Richardson as the No. 94 wide receiver in the nation.
